The central theme of this sūrah focuses on God’s oneness, rejecting all concepts and ideas assigning a son or a partner to Him. It also touches on the important issue of resurrection, intertwined as it is with the concept of God’s oneness. In this, the sūrah follows the same pattern as most, if not all, sūrahs revealed in Makkah.

The sūrah explores its theme through several stories, beginning with that of Zachariah and his son, John, and follows this with the story of Mary and the birth of Jesus. We then have a part of Abraham’s story with his father, followed by brief references to other prophets: Isaac, Jacob, Moses, Aaron, Ishmael, Idrīs, Adam and Noah. These stories take up nearly two-thirds of the sūrah, driving home the truth of God’s oneness, resurrection, the non-existence of any children or partners with God.

They also clearly outline the attitudes towards the prophets of those who follow guidance and those who go astray.

The sūrah also includes some scenes of the Day of Judgement, some arguments against those who deny resurrection, and a reference to the fate of the unbelievers who deny God’s message, both in this life and in the life to come. All this fits perfectly with the drift of the stories the sūrah relates and reinforces its central theme.

The sūrah has its distinctive atmosphere which permeates through all its accounts and pervades its themes.

The sūrah portrays a full range of reaction and feeling within the human soul as also within the universe around it. This world which we imagine to be senseless is shown to have a soul of its own capable of sense and feeling. This adds to the general atmosphere of the sūrah as we see the heavens, the earth and the mountains in anger, reacting so strongly as to almost be rent asunder or levelled down. All this because “people should ascribe a son to the Most Merciful, although it is inconceivable that the Most Merciful should take to Himself son.” (Verses 91-92) Reactions within the human soul are shown throughout the sūrah from start to finish. Its main stories are full of such reactions, particularly in that of Mary and the birth of Jesus.

The sūrah has a distinctive ambience of compassion, contentedness and direct relation with God. It opens with an account of the grace God bestowed on Zachariah, and how he addressed God in a secret appeal: “This is an account of the grace which your Lord bestowed on His servant Zachariah: when he called out to his Lord in the secrecy of his heart.” (Verses 2-3) The words of grace, compassion and their synonyms are frequently mentioned throughout the sūrah, together with God’s attributes of beneficence and mercy. The happiness the believers will enjoy in the life to come is described as love: “As for those who believe and do righteous deeds, God will certainly bestow love on them.” (Verse 96) Among the favours God bestowed on John is that he was compassionate: “We granted him wisdom while he was still a youth, as well as, by Our grace, compassion and purity; and he was [always] righteous.” (Verses 12-13) Similarly, Jesus was, by the grace of God, dutiful to his mother, gentle and friendly in his manners: “He has made me kind to my mother, not haughty or bereft of grace.” (Verse 32)

We indeed feel God’s abounding grace extending over all human life in the vocabulary and sentence structure of the sūrah. We also feel that the whole universe shudders to the sound of the preposterous claims that God has partners. For the universe cannot countenance such absurdity. We recognize that the sūrah has a distinctive musical rhythm and tempo. Even the sound of its vocabulary and the words ending its verses impart a clear sense of ease. Where the context requires firmness, such verse-endings have a doubled, voiced sound of either the plosive or fricative variety, to enhance the impression of firmness or power.

The sūrah provides good examples of variations in cadence, verse- endings and rhymes according to the subject being discussed and the overall atmosphere. At the start, when the sūrah relates its account of the prophets Zachariah and John, the verses rhyme with the syllable, ‘ya’ giving a medium vowel at the end. The same rhyme is maintained throughout the story of Mary and Jesus as well as the brief accounts of other prophets that follow. When these accounts are concluded, the sūrah comments on the truth about Jesus, son of Mary, with the final verdict on his sonship. Here we have a different kind of verse-ending where words with a long ‘ee’ or ‘oo’ vowel are followed by a nasal ‘m’ or ‘n’ giving the impression of a settled and final matter.

When this is complete, the sūrah resumes its accounts of earlier prophets commencing with Abraham and his father. The earlier, easy and gentle rhyme is picked up again until the sūrah begins its discussion of the punishment that awaits those who reject the truth and oppose God’s message and messengers. Here the cadence becomes stronger, and the rhyme changes to be a medium vowel ‘a’ preceded by the voiced, plosive ‘d’ sound. When the attitude of the unbelievers comes in for criticism and denunciation, the rhythm becomes even more powerful, reflected by a doubled ‘d’ sound for the rhyme. Thus the sūrah provides a perfect example of manipulated rhyme and rhythm such that it is in flawless harmony with the overall meaning and atmosphere. Both contribute to the general ambience of the sūrah as it moves with perfect ease from one subject to another.

The whole sūrah may be divided into three parts. The first includes the story of Zachariah and his son John, together with the story of Mary and her son Jesus, culminating in a comment that gives the final verdict on Jesus whose birth and nature were the subject of much controversy among both the Jews and Christians.

The second part includes an episode from Abraham’s life story, in which he dissociated himself from the beliefs of his idolatrous community. It tells how God compensated him with offspring that brought a whole nation into being. It includes brief references to other prophets, those who followed their guidance and those who erred in succeeding generations, explaining the ultimate destiny of both groups. It ends with a declaration that Lordship in the universe is one and the Lord must be worshipped without association of partners with Him: “He is the Lord of the heavens and the earth and all that is between them. Worship Him alone, then, and remain steadfast in His worship. Do you know any whose name is worthy to be mentioned side by side with His?” (Verse 65)

The final part begins with the arguments advanced about resurrection, portraying some scenes from the Day of Judgement. It provides an image of the rejection of all polytheistic claims by the whole universe. It ends with a highly effective scene of the doom of earlier communities: “How many a generation have We destroyed before their time! Can you find a single one of them [now], or hear so much as a whisper of them?” (Verse 98)
